What is the most haunting *film* you have ever watched?

Mine has got to be 'Dreams of a Life', the film about Joyce Vincent, the lady who died in her flat and wasn't discovered for years. It just breaks my heart that she lay there for so long. And the thing that haunts me the most is the fact that her TV was still on.

Another one is 'As Above, So Below' a mediocre 'found footage' film set in the Paris catacombs, although it isn't a brilliant film, it really unnerved me.

I've watched 'Jacobs Ladder' twice in my life,and had unsettled dreams both times. There's something about not being able to distinguish reality that really disturbs me. I'm unnerved watching 'Life on Mars' for the same reason!

I can't believe it, squoosh. I always chunter on about the original The Vanishing on this kind of thread and no one has ever said they've seen it.

Someone ran out of the screening at the end. That will remain my benchmark for an outstanding horror film. Sadly I can't find anything with English subtitles on YouTube but people can probably follow this

I also drone on about La Cabina for horror with a bit of highbrow political allegory thrown in and The Red Balloon which is quite literally uplifting.

Apparently the film makers persuaded the local council to authorise them to let thousands of rats go in the town they were filming in, swearing they'd round them up in some kind of special rat-wrangling rodeo.

Never Let Me Go, the one with Keira Knightly in. I found it very dark and still think about it. Picnic At Hanging Rock just has something about it, always remember that film. Threads terrified me at the time, I would never want to watch it again.Some scenes from Schindler's List have stuck in my mind aswell.

I watched something in secondary school that really creeped me out. I think it might have been Threads. I remember a scene of people hiding under mattresses and another with a woman saying 'sheep don't die of cold.'
